A type of character, action, or situation that occurs over and over in literature; a pattern or example that occurs in literature and life. Example: The emperor himself was an archetype of what the modern world calls a constitutional monarch; he reigned, but did not govern.
Automator is an application developed by Apple for OS X that implements point-and-click (or drag and drop) creation of workflows for automating repetitive tasks into batches for quicker alteration, thus saving time and effort over human intervention to manually change each file separately.
Those more comfortable with programming can, however, embed scripts inside workflows or develop new Automator actions. Once you've created a workflow, you can save and distribute it as a stand-alone application that can be used by others who have Mac OS X 10.4 or later.
